And the best thing about it is it doesn't hold odours. I used to wash my baselayer once a week when I skied every day. And that means you only need to buy one instead of two or three synthetics.
I just bought some north face baselayers to run and ski in...I've got hot chili's too....both of them are ridiculously warm. I really like the North Face stuff alot tho.
I think it's like 196 or 198, it says on the sides of the boxes. It was a round the world sailor who did it - space is at a premium for those guys so the less clothing they have to take, the better.
